Fresh from its $500 million acquisition of satellite specialist Skybox Imaging, Google appears to be ready to make another space-related investment. Sky News reports that the search giant is in advanced talks to take a minority stake in Richard Branson's Virgin Galactic business (which already counted Skybox Imaging as a potential customer) with a view to getting its internet satellite project off the ground. Google may invest around $30 million into the company, which is set to begin commercial flights to space later this year, forming a joint venture that would see Virgin Galactic offer up its technology in return.
